Be-it known that I,- WILLiAM RIoKnmRs, a subject of the Emperor of Germany, re-, siding. at London, in England, have in- .vented certain new and useful Improvements in Explosives, of'which the follow- To all whomit may concern:

ing is a Specification. n 1 According 'to this. invention the explosive compound comprises thecombination of perchlorate ofammonia, a nitrate of an alkali metal either nitrate. of soda or nitrate of potassium, a solid oriliquid product of natural petroleum substantially non-volatile at ordinary temperatures, and a nitrabd coal tar product. It is convenient to proportionate the perchlorate of ammonia and, the nitrate in a manner-already known'so that they are r'elativ'ely always in the same molecular proportions. Further the relative quantities of carbon and oxygen in' the com-. position must be such that as far as possible complete combustion takes place;

The'following maybe given as an ex tynple of the improved explosive:

binding medium in the proportion of to .5%. The explosive may be employed in the form of powder or maybe in solid formv or compressed or otherwise. I V

What I claim as my invention and desire to secure by Letters Patent is 1. In a composition of matter for use as a: blasting explosive, the combination of perchlorate of ammonia, a nitrate of an;

alkali metal, both these substances being in equal molecular proportions, a hydrocarbon of the paraflin series and a nitro-compound of the aromatic series as set forth.

2, Ina composition oi -matter for use as a blasting explosive, the/combination of perchlorate of ammonia,- sodium nitrate, these-two substances being in equal molec-- ular proportions, -paraffin and trinitrotoluene as set' forth;

' 3.- In arcomposi tion of matter for use as a blasting explosive, the combination of perchlorate of' anirnonia., sodium nitrate,

these two substances being in equalymolee ular proportions, paraflin, trinitrotoluene and a binding medium asset forth.

4. A composition of matter for use as a 'Parafiin a'xnu 13% Trinitrotoluene 1 14% Perchlorate of ammonia l' i 42% Sodium nit-rate 31% blasting explosive, combined in approxicent.' sodium nitrate, 13 per cent. parafiin wax and 14 percent. trinitrotoluene as setforth.
